Part of lettering on gold medal, perhaps (4)
I believe the answer is:
gong
'medal perhaps' is the definition.
(I know that award medal is a class of award)
'part of lettering on gold' is the wordplay.
'part of' indicates a hidden word.
'GONG' can be found hidden inside 'lettering on gold'.
(Other definitions for gong that I've seen before include "Wordsworth's Boy; Dostoevsky's hero" , "Round metal plate struck to resound" , "Percussion instrument - medal (slang)" , "Decoration" , "Medal (sl.)" .)
